A Note On \((m,2,m-1,\frac{m-2}{2})\) Relative Difference Sets

In this note, we obtain nonexistence results for \((m,2,m-1,\frac{m-2}{2})\) relative difference sets. In particular, we obtain further restriction on the parameters of splitting \((m,2,m-1,\frac{m-2}{2})\) relative difference set under certain condition.
